I just got a never used 7130. I installed the software on my Vista laptop following instructions, but when I connect my BB with the included USB cable it does not connect with my computer. the desk top manager is 4.1.1.9. When I click on "intellisync"/options/connection settings, connection is set at USB but when I click "detect" I get a message make sure device is connected, devise not found.

How do I fix this, or how do I erase all installation from my computer, including drivers, to get a brand new install?

So I uninstalled the desktop manager, downloaded 4.2 from the blackberry support page, and my computer will not run it. Comes up with an error message "you do not have permission to run this software on this machine".
I have never had that message before, and I can install 4.1 from the blackberry website. Is there another download for this program somewhere or how do I get beyond this?
